Why does JMP 10 create a new instance of JMP when opening a data table?

Anonymous — Fri, 08 Dec 2017 16:38:35 GMT

I am using JMP 10.0.2. Whenever i open a data table (from the desktop, an email, etc.) JMP launches a new instance of JMP instead of opening the data table within an existing instance. Is there anyway to change this behavior?

I believe you can correct this with the following.

Exit out of all JMP sessions that are running
Run the JMP version you wish to use as the default JMP version (if you happen to have multiple JMP versions installed on your machine)
Go to File-->Preferences-->Windows Specific, then click on the Reset Associations button near the bottom of the dialog window

That should fix the Windows Registry to associate the current JMP session with JMP files.

Now try double clicking on your files and see if it behaves as expected.

Let us know if that fixes it.

I followed the instructions and the problem still exists. I get multiple instances of JMP 10.0.2 when i open JMP data tables by double clicking on them instead of the data tables being open in the same instance of JMP 10.0.2.

Please try the steps outlined in this Winter 2011 JMPer Cable article, page 7:

http://www.jmp.com/about/newsletters/jmpercable/pdf/27_winter_2011.pdf

The steps outlined in that article should fix file type association issues for most cases. However, if you still are having an issue, please follow up by submitting a Technical Support track with us.

I'm encountering a similar issue when trying to associate .csv files with JMP in Windows 7 environment.

I successfully associated the .csv file type with the JMP Application. However, when I double click a .csv file, a new instance of JMP is launched - JMP, JMP [2], JMP [3], etc.

This does not happen when opening a .jmp data file, as .jmp files open into the "oldest" open JMP application running, e.g. JMP or JMP [2] if no JMP instance.

Is there something that needs to be added to the file assocation to force a .csv file to open into an already running JMP instance if available?

When reviewing the question and answers it looks to me they are not belonging to eacht other.

What I extract is:

The File-associations in Windows are a way to tell wich program to start for that file. That is working well.
The answer getting back is about correcting those file-associations.

The question/issue is that clicking on file in Windows will open up a new program every time. That is quit normal behavior (try word or others).

The file association can tell wich program to start, it does not know and cannot know (random pid) whether a program is already running.

Only with a smart inter-process communication set up this can be solved. Question: Is JMP having this option?

Starting open a file from within a running program (JMP or ohters) does know itself the own procecess id, pid).

In that approach very easy to open up multiple files by himself.
Solution:

Instead of double clicking the easiest approach could be drag-drop the file to a running JMP process.

I disagree, each time you open an Excel file it doesn't launch a new instance of Excel. This allows you to move data from worksheet to worksheet.

I found that the Widnows Registry was as follows (for Windows 7):

HKEY_CLASS_ROOT\JMP.Document\shell\open\command = C:\Program Files\SAS\JMP\10\jmp.exe /shellopen "%1"

I changed this to:

HKEY_CLASS_ROOT\JMP.Document\shell\open\command = C:\Program Files\SAS\JMP\10\jmp.exe /shellopen

This appears to fix the issue where it would open a new instance of JMP each time you double click on a file.

I'm having the same issue with JMP11.2 64bit. I had JMP9.0.2 installed in parallel for awhile. The multiple instance behavior only started when I uninstalled JMP9. I've gone thru the reset file associations instructions including manually merging the .reg into my registry but no change in behavior. Editing the reg key per the above (removing "%1") didn't work either.

I can't find any new settings in Preferences that would govern this behavior. I certainly don't need a unique JMP home window for each file I open.

JMP9 never exhibited this behavior. When I had JMP9 and 11 co-installed I didn't have this behavior. It was after I uninstalled JMP9 it started. I had to reassociated the file extensions at that time as well.

Hi mikehd,

this is an unusual behaviour. I tried to reproduce but couldn't. The ony time I got a new instance is the following:

I have both JMP 10 and JMP 11 on my machine, 11 installed obviously after 10. Let's say I'm working in my old version of JMP 10 because of a current Long-term Project. Now I want to open a new file by double clicking that file in the Explorer window. This new file launches JMP 11 as new instance.This is becuase the files are linked to the most current Version of JMP unless set otherwise by file associations.

I'd recommend to contact Support@jmp.com to follow up this behaviour. It would be great if you could post the reason for that behaviour in case they hopefully can help you to fix it.

Best, Martin

Hi Martin,

I have been using JMP for 2 years but still couldn't find fix to this issue. I think JMP has fixed this issue while opening .jmp data in newer version but it still exists for other files.

Reproduce the problem: Associate .sas7bdat (or any other files like .csv, .txt etc) to open by default with JMP in windows 7. And now try opening multiple files.

Re: why does JMP 10 create a new instance when opening a data table

Hi Gupta,

Besides the question why at all you want to default to JMP when opening files like .csv, .txt, .sas7bdat here is what I would say to that:

If you have an instant open, just drag those files in any open JMP window and this will open the files in that session without opening new instances (I've tried this just a Minute ago to be sure)
Use File -> Open and select all files you want to open at the same time, click open and all should open in the same instance (also tried to be sure)

However although I realy do not see a good reason to have all kind of data files to be open in JMP automatically (besides just double clicking). if that's what you want to do I higghly recommend that you Change the way of opening multiple files. First start a JMP session and then drag and drop those files into any JMP Window.

As JMP will recognize JMP related files automatically I guess JMP is not set-up to handle or recognize other files automatically in the same instance. personally I wouldn't cound this as a bug. However you can Report this to our Support Team so the developers get that tracked in their System and can consider changing something for the future.

Hope this helps,

Martin

Thanks, this worked for me. After installing jmp13 I started having multiple jmp Home windows open every time I opened a .jmp or .jsl file from windows explorer. Using the various options to reset defaults in the Prefrerence windows did not resolve the issue.

Please review Problem Note 52261: New instance of JMP® is opened each time a new file is opened which discusses ways to correct this behavior. If none of the solutions resolve the issue, we recommend doing a full uninstall and reinstall of JMP.

This is not the solution to this problem, but is the solution to another problem not related to this one.

I am having this isse after installing jmp15 on windows 10. The preferred program settings are set up correctly, I just don;t want all these versions of JMP open - and did not have this issue before installing version 15.

How do I get to this windows register where I need to make this change?

Have you tried going to the Preferences and Resetting the Associations

File==>Preferences==>Window Specific

then click on the button at the bottom of the options labelled "Reset Associations"

Re: why does JMP 10 create a new instance when opening a data table

Mo — Thu, 14 Nov 2019 17:11:40 GMT

Yes, I tried that. The association with theprogram is there, it just opens the new instance of JMP. My coworkers just installed JMP 15 as well, but did not uninstall JMP 14, and they did not encounter this issue, that is, when they clicked on a jmp data table in their file explorer, it would just open the data table in the already openversion of JMP.

I'm wondering if the uninstallation of JMP14 messed something up...

I was able to make it work! After installing JMP15, everything worked fine. On uninstalling previous versions of JMP, when opening a jmp table from file explorer, windows would ask to select an app to open this file. When you do this through this windows prompt, it will cause a new occurence of JMP to open each time you open a jmp data table from file explorer. Resetting file associations didn't help, uninstalling/reinstalling didn't help - windows seemed to remember this choice, no matter what.

However, if right after the JMP 15 install and after the uninstall of the previous version you go to JMP 15/preferences/windows specific, and then reset the file associations there, this issue does not occur, and clicking on a JMP table in file explorer opens just the data table (with JMP already open), and not a new occurence in JMP. We were able to try this out as we had multiple coworkers installing 15 and uninstalling older versions.

SInce I had already done the windows propmted file association, I needed to go into the windows registry. We emptied the Computer\HKEY_CLASSES_ROOT\JMP.Document\shell\open\command default value, and backed out, then went to JMP and reset the associations under preferences. It worked! The same value appeared in the registry again, but it worked. I can now, with JMP open, open up JMP data tables again from file explorer in the JMP version that is open without having multiple occurences of JMP open up. Just sharing in case someone runs into this, as it really bugged me, and took me a good portion of the day (and willing coworkers that didn't mind me doing stuff on their computers) to figure this out.
