change default runtime engine

[paul_s]

I have run into some issues with an exe built in v6.0.2 after installing LabVIEW 7 (alongside 6.0). The front panel is garbled etc, and when the exe is run it appears to use the 7.0 rte instead of the 6.0 rte - changing the name of the 7.0 directory (../shared/labview runtime) results in labview looking for the 7.0 rte msi installer. (instead of finding 6.0 rte) Can I change the default rte to 6.0 version? Any help appreciated

I don't believe its' possible for a 6.0.2 exe to use anything but a 6.0.2 rte. If you have access to the About item on the Help menu, it should say which rte is being used. I have 7.0 installed along with 6.1 and haven't seen any problems launching 6.1, 6.0, or 5.1 executables. It's possible that the rte has been corrupted somehow or one of the support files. Are all controls and indicators garbled or just specific ones? Have you tried reinstalling the 6.0 rte?

Thanks Dennis, I believe something has been corrupted. I have uninstalled 7.0 for the time being, however every time I start LabVIEW 6.0.2 now the "windows is preparing to install" dialog flashes up, and then msiexec.exe is running continuously in task manager. (I also noticed this when running exe before removing 7.0) I don't know what has caused this. Basically the garbling consists of tab controls transparent but operable by clicking on text, boolean controls invisible, and control borders invisible... I think I will reformat at this stage, unless you know what is causing msiexec to launch each time? I will attach the msi log if you care to take a look. I will try reinstall of rte as well

One way to avoid a conflict among different versions of the RTE is to group
your executables of like version in a single directory (perhaps called
binG_V# ?) and load the correct RTE there. Then redo your shortcuts to
point to the executables in the new directory.

repair of v6 (after deleting transforms in registry) has fixed msiexec problem, and my exe now works properly, thanks for help
