Trouble Getting Oscar to Run on Windows 10 - kcw196 - 04-16-2021

I have been trying to migrate an Oscar installation to a new laptop running Windows 10 using Oscar 1.2.  While it runs fine on my old laptop, I have had no success on my new laptop.  Regardless of what I have tried the app is hanging on the profile selection screen.

After reading a number of other threads, and trying a number of migration scenarios, I have narrowed the problem to this.

  • Oscar 1.2 installed on laptop

  • Data location c:\Oscar_Data so no OneDrive involved.  Not sure if that matters.

  • Tried both (A) importing the existing data, and (B) not importing the existing data, and creating a new profile.

  • In both cases, Oscar then takes me to the profile selection screen.  Open and Edit profile are greyed out.  New profile not working.  Can't select the displayed profile.  None of the options under view are working.  If I minimize the app and then reopen it the screen is not repainted, so it appears that app is hung.
Any ideas what is going on and/or what to try next?

Thanks.

Try holding down the SHIFT key when you start OSCAR. This will force OSCAR to use a different graphics engine that might be more successful.

If OSCAR is hung, this probably won't work, but try it anyway: Turn on Help/Troubleshooting/Show Debug pane. Stop OSCAR and restart it. When you get stuck, copy the debug pane (Ctrl-A, Ctrl-C) and attach it to a reply to this post. Let's see if the debug messages shed any light on the problem.

A final option it to purge the OSCAR data in the repository so it doesn't remember the location of OSCAR_Data, graphics engine to be used, or other system data.  Try this: Download https://www.sleepfiles.com/OSCAR/Patch/CleanRegistry.reg to your desktop, then double click on CleanRegistry.reg to patch the Windows registry to remove all OSCAR parameters. Specifically, this removes the memory of where the OSCAR_Data directory is.

Let us know what works, or doesn't.

Thanks for the quick response and your help. 

Cleaning the registry solved the problem.

Thanks
