Hello,

Since the update to version 0.90, I can't do update, Ihave a window with "freshclam.exe can't start normaly. Error 0xc0000034".

I shut down : Windows defender, Firewall. Same problem.

No other Security programs (Virus, Spyware, .......) on my pc.

Thank you for your help. Christophe.

it sounds like a msvc runtime library problem. Try to rename "C:\Program Files\ClamWin\bin\Microsoft.VC80.CRT" to something like "Microsoft.VC80.CRT.bak" and run freshclam. If that doesn't help, install this:
