@Intuit_hieu  are you still the one to tag for weird install issues like this? @IntuitGabi or maybe you can get one of the programming guys to look at this, I think its outside of any fellow users knowledge base.  I feel like there was another guy that was helping with program issues like this, but I cant remember his name!

Laura, you may want to Edit your post and include more details, looks like they didnt quite make it into the body of the post.

Thanks! I was having issue with the post. I just updated it.

I'm sorry, but where do I find that file? I don't see anything with that name

They should be under something like c:\prowin22\common folder

Use Windows File Manager, find the ProSeries2022 folder and the files should be in the Common folder under Proseries 2022

I just deleted them and tried to get into the program and it worked!!! Thank you, thank you, thank you!! 

Woohoo! @Intuit_hieu  you da man!  or woman!  😁

We have this error with multiple computers this morning.  I went to my ProWin22 folder & do not have a "common folder".  Can anyone help?

I found the common folder on our network, but we cannot delete the Callisto files. The OPT file won't delete - says it is in use.  The others delete, but reappear as soon as we try to log in to PS.  

@karey Looks like you have network install.

For network install you may find it in the shared location, e.g. C:\ProSeries\ProNet22\common

I'm having the same problem.  It won't let me delete the .opt file and the others reappear when i try to open ProSeries22.
