Win95.exe file has an 'open with' association

September 18, 2010 at 07:57:13
Specs: Windows 95
I can't start any .exe file. Everytime I click on an application I get a dialogue box saying 'Can't file WUEWRGV.EXE' 'this file is needed to run all applications'.... Me thinks a virus?

I deleted guergrv.exe last week and now can't open any application or shortcut. When I go to My Computer, view, file extensions tab it shows .exe as having an 'open with' association with WUEWRGV.EXE. I have deleted this file and can't get it back.

I can't delete or edit the association; the buttons are greyed out.

I can't use regedit.exe as it can't find wuewrgv.exe to start it!!!

Have no disc's to re-install Windows 96....

What to do la??

Tricky because most of the old fixes for W95 have vanished from Google.

If a virus has disabled regedit then you should be able to workaround it by renaming regedit.exe to and using that. Usually viruses attack exe files but not com files and regedit works just as well with a com extension. Take a security copy of regedit.exe and file it away first just to be on the safe side.

Unfortunately W95 has a rotten registry restore (you rename user.da0 and system.da0 to user.dat and system.dat respectively). You could try this but make sure you save the user.dat and system.dat files first, so that they can be restored if it backfires. Mostly, by the time you do this the original registry files have been overwritten - you only get one chance.

If you manage to get the beast working I can provide batch files to give you a workable registry save/restore feature which works on W95 or W98.

If push comes to shove you could format and put on W98SE - the CD's are often found on eBay. Before taking that risk you would have to make darned sure your machine can handle it and that you can get suitable drivers. W98SE is far better than W95 and you get 5 registry saves with that. Then there is always Linux (such as Knoppix)...

Neither wuewrgv.exe or guergrv.exe turn up any google hits except this one so it's probably a virus but make sure you're spelling it/them right.

We'd use EXEFIX08 for problems with 9X exe file associations but I couldn't find a working download site. But do a google search for EXEFIX08.ZIP and see if you can find it. If not I can email it to you.

The zip file contains exefix08 as .inf, .reg. and .com files given the difficulty in installing the fix via an .exe file as well as instructions.

Oops, I was just about to offer you file, then noticed DAVE had done so.

The rust is flying off LOL (well, my old notes are good).

Here's another way forward. Copy the text between the following lines into NotePad
and save it as Fix.reg

@="\"%1\" %*"

@="\"%1\" %*"

Make sure there is either one or two (max) line spaces at the end (as shown).
Double click the file and it will do the same as Exefix08, provided that your system
will accept a reg file.

Guys...thank you all so much for your swift and helpful replies. The incriminating file is wuewrgv.exe and on further investigation the association problem with the .exe file exists with the .com, .reg, .bat and .scr file extensions too. i.e they all 'open with' wuewrvg.exe and the remove and edit buttons have been greyed out.

Derek I'm going to try your final suggestion. I'll let you know what happens. Txs

I think with .reg files you right click on them and then choose 'merge'. That should bypass any 'open with' requests.

Either double click (accepting prompts) or right click and merge would work "normally" but in the circumstances I agree that merge is probably a better option.

All those broken associations were common with the Swen virus, there was a Swenfix.inf file for the fix. Copy, Paste, and Save As Swenfix.inf file then right click it and choose to install it.

Watch out for word wrap, and the same blank line cautions as Derek's #4 apply here as well. If this does not work for you, a pair of reg files can do the same job if you apply them in Autoexec.bat file at boot up time which WILL work for sure - let me know if you need them.

You really should buy a used CD on ebay for peanuts...
