FreeCommander Forum

Hi,

since a fresh install of Win7 (64 Bit), my FreeCommander crashes regularly, sometimes after some file action, sometimes even after hours of idle without having anything done with it.

I did a clean re-install, and a "sfc scannow". All is ok...

Any hints?

Thx,
Dietmar

@dietmar: could you try the portable version and see if the problem persists?

Hi,

thanks Karol, but as I said, "sfc scannow" is ok.
I must admit that I did not test the RAM yet, but I don't think it is a hardware problem since the hardware didn't change and the problem occurs now after a fresh installation...

I will test the portable version and let you know!

Thx,
Dietmar

Hi,

using the portable version did not help much... It crashes not that many times but always several times during some hours... annoying. I really liked FC and got used to it for years now, but I fear that I will have to take a look at other file managers

The main difference is, that the portable FC mostly crashes without any debug output - it just hangs ("application not answering and needs to be closed") or even has to be killed manually.

I only managed by luck to get one debug output, which looks quite similar to the one I posted above...

Sorry to hear that! I understand your feelings, but you also have to understand that this is not easy to fix if it can't be replicated by others.
Just one more question: do you have Service Pack 1 installed for your Windows 7 (in other words, is your win7 to date)?

Yes, it has SP1 and has all MS updates applied...

Since it is the only program that crashes regularly and so often, and since it started after a fresh reinstall of Win7, I don't assume a hardware (e.g. RAM) error here.

Ok, since it seems to be not resolvable, I will sadly turn around and try other file managers
