Title: ERRORS WITH MSVCI70.DLL and MFC70.DLL
Post by: Jedidor on October 29, 2004, 11:40:47 PM: If anyone comes across these errors I am posting this to be helpful you can download the files needed at

http://www.e-systems.ro/download-dll/mfc70.dll/
http://www.e-systems.ro/download-dll/msvcr70.dll/
http://www.e-systems.ro/download-dll/msvcp70.dll/
http://www.e-systems.ro/download-dll/msvci.dll/

Since you have no virus scanners due to a lack of those files and they come in ZIP archives you will to just have to trust another avast users judgement. You need to past those files once extracted in your system32 folder in the main windows directory.

Post by: Eddy on October 29, 2004, 11:53:50 PM: Avast was compiled using MS Visual Studio.NET, that is, for the case of Avast, these files would be called msvcr70.dll and msvcp70.dll.

So just install it from the MS website.
This has been explained in several threads on this board already. Use the search function to find them.

Post by: Vlk on October 30, 2004, 12:04:03 AM: Jedidor, are you having problems with any of these files? I mean, all files necessary for avast to function (including some of the files you quoted) are included in the avast setup package and should be installed automatically.

What's the problem then? :)

Thanks
Vlk

Post by: Notromda on October 30, 2004, 02:21:10 AM: I'm sorry, I didn't provide any details. Windows XP SP 2, I have not installed the .NET updates.

Post by: Eddy on October 30, 2004, 02:25:46 AM: Try a repair of Avast. start > control panel > programs > add/remove > Avast > change/repair. If that solved the problem, I suggest you upgrade to 4.5 beta
Title: Re:ERRORS WITH MSVCI70.DLL and MFC70.DLL
Post by: Notromda on October 30, 2004, 02:28:43 AM: I went ahead and installed the .NET update...
Title: Re:ERRORS WITH MSVCI70.DLL and MFC70.DLL
Post by: Notromda on October 30, 2004, 02:36:43 AM: Installed the .NET update, and it still can't find SVCP70.dll

Tried the repair operation... it didn't do much of anything, and still get the same error.

I guess I'll try the beta.

I'm kinda surprised, this is as basic a windows XP install as you get. Most of the time I run Linux. ;)

... and where do I download the beta from?

Post by: Eddy on October 30, 2004, 02:53:53 AM: If Avast doesn't work you can not upgrade. Remove Avast completely using the Uninstall Util (http://www.avast.com/eng/download/programs/avast_uninstall_util.html), reboot, install Avast. See if that solves it.

Post by: Notromda on October 30, 2004, 03:06:51 AM: Just read it, but it doesn't give any new info.

I've done all that.
Title: Re:ERRORS WITH MSVCI70.DLL and MFC70.DLL
Post by: Notromda on October 30, 2004, 03:10:53 AM: I just searched for the fille, msvci70.dll, and it does not show up on my system.

Search for the MS visual c runtime.

Post by: annie_w on October 30, 2004, 03:31:08 AM: Same problem here on a freshly formatted XP Home, no SPs yet or anything. Reinstalling didn't work but downloading those files above did - just a note though - the last link on the list should be

http://www.e-systems.ro/download-dll/msvci70.dll/ (http://www.e-systems.ro/download-dll/msvci70.dll/)

Excuse me? Why should I have to install Visual Studio? This is a plain old WinXP system, and I'm trying to keep intalls to a minimum. Is Avast not capable of packaging their software right?

I think I'll go back to AVG.

Only thing Vic said was that avast should have installed the files automatically. It didn't.

There are no MVVC* files in C:\Program Files\Alwil Software\Avast4, as that indicates there should be. So the Avast installer apparently did *not* install those files.

Title: Re:ERRORS WITH MSVCI70.DLL and MFC70.DLL
Post by: techie101 on October 30, 2004, 05:01:40 AM: I have found from personal experience that the problem lies not in the file being missing, but in Avast being unable to update the file during upacking.

This is usually due to the fact that Windows "stamps" the files as read only.

Do a system search for ALL dll files to locate the files msvcr70 and 71, and MSVCI70.DLL and MFC70.DLL
These files should be located in the C:/windows/system folder.
Right click on each file to display the dialog box. If either file/s are "read only', uncheck them.

Then do a manual update of Avast.

Post by: Vlk on October 30, 2004, 11:04:31 AM: Hi, it was actually a problem with the 4.1.501 setups. It will be fixed in a while.

If you're still interested in using avast, please re-download the installation package in about an hour and retry the install.

Thank you and sorry for the inconvenience.
