Areca Backup on 64-bit Windows

Areca is an excellent open source cross platform backup utility. Combine it with an FTPS server and you have a secure, available anywhere backup system. In other words, your own free cloud backup solution.

However, Areca does not officially support 64-bit operating systems. This does NOT mean, however, that you can not run Areca on a 64-bit system.

First, even with 64-bit Java runtime installed, Areca will not see that java is there.
The solution is to install the x86 version of Java.

Next, when launching, you will get the dreaded
"msvcr71.dll not found" error.

The solution is to do a search for the mscr71.dll on your system. It is there, especially if you have Office installed. If you can't find it, you need to enable "Show system files" in the folder and search properties.

Copy this file into
C:\Windows\SysWOW64 and everything should work.

I hope one day the Areca folks will create a 64-bit build. But until then, this is an easy work around to enable 32-bit Areca on your system.

Very useful article!

I'm using Win 7 64-bit and wouldn't have got it working otherwise.

I got the DLL file from http://www.dll-files.com/dllindex/dll-files.shtml?msvcr71

Thank you! Not that I've tested anything extensively, but I no longer receive the dll error message .

I am using windows 7 and had the same problem. I fixed it by installing the 32 bit version of Java.
