missingC:\Windows\system32\msvcr70.dll

Hi I found I could not open a number of software programmes so investigated reason and on using "recuva" to check on recoverable deleted files it told me that the file (MSVCR70.DLL) was unrecoverable. giving its path as: C:\WINDOWS\SYSWOW64\

I think the problem here was most likely that the MSVCR70.DLL was actually missing from the original Windows OS installation ie. this was not a fault or anything that could be fixed by using System File Checker.

There are definitely a few DLLs that I've needed to be able to run certain niche bits of software which were simply not included with Windows 7 Pro 64bit. That OS was installed correctly, registered and fully updated about 18 months ago and kept updated.

I wanted to use one particular program soon afterwards that had been working perfectly on my WinXP 32bit laptop but received an error message as the OP describes but in this case about MSVCR71.DLL. With a little research I found where to look in the Windows folder to find it but it simply wasn't there.

At the time it was a month old installation so about as fresh as it gets. Further research suggested it was/is well known that certain DLLs, like that, which were included with WinXP or the bundled software were not included with Win7.

Some users had done a full OS reinstall because of the advice they'd been given and when they looked for the missing DLL afterwards..........it was still missing.

Unless you have source for the DLL ie. an old computer then you need to find a reliable download and install it yourself. All the usual precautions for downloading stuff like this should be followed. The best web sites including checksum information. I'd also put in a Restore Point beforehand too.

The three missing DLLs I have needed, including MSVCR70.DLL, are all 32bit so they go in the C:\Windows\system32 folder even on a 64bit machine. I don't think it actually matters if you put it in C:\Windows\SysWOW64. In fact several apparently authoritative sources suggest installing it in both those folders. I suspect whatever program requires the DLL will look for it in both anyway.

The crock of stuff out there (OS system corruption, registry faults, viruses etc etc - all the usual suspects) about missing DLLs and what to do about it is enough to frighten anybody. But when you are told something is missing why immediately think there is a problem? It may just be missing because it was not there in the first place and, from all the evidence I've found, that does seem to be the case with MSVCR70.DLL and MSVCR71.DLL.

Hi......Thanks BossDweebe for your quick response.

I tried System Restore in the first instance but as usual it would not restore from several restore points, saying( "unspecified error (0x80070005)" whatever that is....not very helpful

I re-installed the programmes which would not open (using the desktop shortcut) and that has proved positive, however things are not working as smoothly as they were i.e. slow responses.

I purchased my copy of Win 8 ( I updated it to Win 8.1) directly from Microsoft, via the website so do not have a hard copy with which to a "repair" which I feel is probably my best hope. How does one get a hard copy.

Having found this forum my next search for answers will be to find out how to get "System Restore" on my Laptop to function properly.

Thanks again for your help....

There is no MSVCR70 in either System 32 or sysWOW64 on my machine. There are the newer

MSVCR71 and 100, however.

It looks like this is an old version, probably installed by one of the software you are using.

There are a couple of options -

• If you have a System Restore point from before you think you accidentally deleted

(and apparently emptied the recycle bin), try doing a restore.

• Try reinstalling one of the programs that use this .dll .
• Run Windows update. An update may install this .dll .
• If you use a Registry 'cleaner' it may have deleted the registry key. Use the registry

backup that is should have made to restore the registry, and uninstall the registry 'cleaner'.

• If you get desperate and you have a Windows install disk you could do a 'repair' reinstall

(not nearly as painful as a full reinstall)

Or use the 'recovery' partition, if you are using an OEM  machine (HP, DELL, etc) or laptop.
