Thanks for the suggestion. I think I started this thread before the last update came out. I am definitely running version 0.5.0.10415 now, and am still unable to install the backup app.

Follow the steps below:

1) Stop Tonido
2) Click Start -> Run -> type "%APPDATA%/Tonido/plugins"
3) Remove directory "backup", if there is one
4) Start Tonido
5) Try installing Backup
6) If you are still having problems, please post the log again. Make sure to post the log after you attempted to install Backup.

OK, I followed your steps. Still getting the same error message when I try to activate Backup. Here is the log:

Hmm, this is definitely odd. We run XP SP3 on our development machines and we don't see this issue.

We have to investigate this a bit more.

same problem here but with a different OS:

Windows Server 2003 R2 SP2 Enterprise edition

I know it states that Tonido works on XP, but the rest of Tonido and all other applications work fine?

Cheers

The same happens on a XP SP2 machine, unable to install and run backup. Same error

I have kept trying to get this working. I have tried SP2 and SP3 on this same machine, but keep getting the same results......

We found the problem and it is with the compiler settings which were different. We will release in a few weeks.

Thanks guys for following that up. It is much appreciated, cannot wait to get the update
