[Equest-users] eQuest Error on Opening - Invalid Previous Run Date

Wed Dec 17 11:57:17 PST 2025

 I installed the new eQuest.ini file. I look in the data file, and the old one is still there. Once I remove that old file, the program runs..until I close it and have to do the removal process all over again.
Am I missing a step?
Look up the movie..Colossus, the Forbin Project. 1970. AI predicted.

 Amazing. Read-only solved it for now. God bless both of you. Cheers!

My colleague, Eric Rubli, has a much more elegant and less laborious solution.  Once you have a working eQUEST.ini file … set it to READ ONLY in properties. 

For us, that means eQUEST continues to open as previously expected without having to recopy or edit eQUEST.ini.

Older (working) eQUEST.ini attached.

Thanks Brian. Any chance you can share your old .INI, if you don't mind?

I am also seeing the issue.

It seems to be something being written to eQUEST.ini.  I can get around it by having a “clean” copy of eQUEST.ini (with a date before today’s) and replacing eQUEST.ini with the clean version before opening eQUEST each time. (which is still a pain but better than reinstalling)

Same here, including the un/install actions. The note appeared just this morning!

I also opened it once, but not again!

Any ideas would be great!

Thank you!

Hi All

I am having issues with eQuest I haven’t seen in all of my 15 years of eQuest.

After the first time it happened I uninstalled, reinstalled and it worked 1st time but on closing eQuest and opening it back up again I get this message

Anyone have a fix for this?

Thank you!!!!!!
