"TDMS Open.vi" won't open file if not administrator

I have an app that I install and run from a subFolder of the program files folder, and there's a TDMS file that installs alongside it (it's a set of pattern match data that the app needs).  When the app calls "TDMS Open.vi" everything works fine if I'm logged on as an administrator, but I get an error 8 (file permission error).if I'm not.

 

When I'm not an admin, I can run the exe that's in the same folder - why can't that exe then load the TDMS file?  What am I missing here?

I wonder if it's because opening the TDMS file results in an index file being created, and the user doesn't have permission to write to that folder?

 

The file just has some pattern match data in it that only my software will access - is it possible to turn off the creation of index files in this case?

I suppose I could switch from TDMS to TDM - those files don't have index children, right?  That'd be a lot of work though...

 

Why do I feel like I'm having an ACME Do-It-Yourself conversation? 🙂

That's because you are used to LAVA.

 

We have trouble spelling TDMS or LVOOP on this forum. Smiley Sad

 

Just granting write access is not acceptable I suppose. 

 

Herbert would know.

Meh.  My workaround is to copy the TDMS file to a location that the user can write to (a defined location within their My Documents), read the file, then delete it.  It's dirty, but it works.

I just digged up a longer discussion from my bookmarks on that issue. I hope it helps
