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

Sun Jan 4 18:22:30 PST 2026

Hi All,
I am not sure if this would help. I really wanted the equest to run in DOE 2.2 and to avoid constantly resetting to zero please see if this would work.
Step 1: Open Notepad
Step2: Look for the locations of eQuest.ini in the documents folder and eQuest.exe in the program files.
Step 3: Copy command below at echo offsetlocal
set "INI=C:\Users\16476\Documents\eQUEST 3-65-7175 Data\eQUEST.ini"set "EXE=C:\Program Files (x86)\eQUEST 3-65-7175\eQUEST.exe"
powershell -NoProfile -ExecutionPolicy Bypass -Command "$ini='%INI%'; $exe='%EXE%'; if(!(Test-Path -LiteralPath $ini)){Write-Host 'ERROR: INI not found' -ForegroundColor Red; exit 2}; if(!(Test-Path -LiteralPath $exe)){Write-Host 'ERROR: EXE not found' -ForegroundColor Red; exit 3}; $t=Get-Content -LiteralPath $ini; $t2=$t -replace '^\s*Status\s*=.*','Status=0'; Set-Content -LiteralPath $ini -Value $t2 -Encoding ASCII; Write-Host 'OK: Status forced to 0' -ForegroundColor Green; Start-Process -FilePath $exe;"
endlocal

 Step 4. Save as: Run_eQUEST_Fix.bat
Step 5: click the command prompt i will reset to zero and open eQuest.
I hope this helps.

Thank you so much!

I was changing the wrong .ini file.

P.S. This fix is not needed when opening eQUEST in DOE-2.3 mode, but needs to be applied after any open in DOE-2.2 mode even when that open was just to switch to DOE-2.3 mode.

Hi Everyone,

Temporary solution for DOE-2.2 per communication with Jeff (it works I tried it).

In the equest.ini, in the [Registration} section at the bottom, if you set
Status=0
before stating eQUEST, when DOE-2.2 is selected for the simulation engine (not an issue with DOE-2.3 selected), should cause a registration dialog with a valid registration number to be displayed instead, then you should be able to click OK and it should startup normally. Some suggested using the original equest.ini before starting it the first time and setting the file to be read only; but that prevents saving other information about the last use rather than having the startup just ignore previous date information.

Applies eQUEST.ini located in the C:\Users\"your user name"\Documents\eQUEST 3-65-7175 Data\

You can keep it open in Notepad and just reset the status to 0 each time before re-opening eQUEST.

My team started having issues after a Windows 11update. Not everyone, but most.

Kidding / not-kidding – the covert effort to kill off eQuest continues…..

Just curious, is everyone referring to or using eQuest DOE 2.3? The fixes discussed have not worked for me (Doe 2.2).

Also, this is the only content of my .ini file:

Thanks Brian for this temporary fix. Your approach is indeed working. 

I replaced the INI file after closing equest few times. It did end up opening every time.

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!!!!!!
