WAMP shows error 'MSVCR100.dll' is missing

Question

When I tried to install WAMP, that popped up the following alert,

I clicked OK, it continued to install WAMP. When I start, the WAMP logo is always 'yellow'. It isn't turning 'green', meaning there's something wrong. What exactly is the MSVCR100.dll file? How do I obtain it and fix this error?

Answer 1

To solve this issue you have to install all Microsoft redistribution packages 2010,2012(x86 and x64) than uninstall wampserver from control panel and reinstall new copy of wamp server this error will be get fixed

Answer 2

Edit: Since I have encountered the same issue again, I have noticed that my previous solution did not work; as well as any other solution posted here. I am using Windows 7 Professional (64 Bit).

This time, I have placed the 'MSVCR100.dll'file (downloaded as a ZIP, then extracted onto Desktop and then copied) into a C:\Windows folder http://www.dll-files.com/dllindex/dll-files.shtml?msvcr110

and then installer WAMP Server, 64BIT. http://sourceforge.net/projects/wampserver/

Then, I have downloaded and installed: http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679

filename: vcredist_x64.exe

I have only tested it with the PHP from a command-prompt, since I do everything else on a server and not a local-host.

Although it works for what I need to use it

Running:

php gives Failed loading php_xdebug-2.2.5-5.5-vc11.dll

php -v -WORKS!

Please let me know if this worked for you or not or if there is something else I need to do to improve the fix.

Answer 4

Just ran on this issue. Issue was at same OS (Win7 HB x64) as in this answer. I used gaurav's advice and successfully started WAMP.

I wanted to add that you don't need Visual C++ 2010 versions when using 2012 version (at least in this case).

Answer 5

For me none of the above answers worked so I am adding what worked for me. I first installed the files mentioned in the accepted answer and when that not worked, I downloaded files from this link and it started working.

So I think 2012 distribution is also needed (I am using window7 home basic 64 FYI).

Answer 6

After downloading all the libraries said by ezaoutis, the error message on my windows 10 persisted, reading the wampserver3.1.3 installation requirements, there was a verification tool called check_vcredist.exe , i ran it and it show me all the missing libraries and it's download links, so i finally could install it succesfully.
