Windows 7 - Problems with .iso and .rar files

The only daemon tools I can find that is 64 bit is 4.09, released in 2007. DTLite V4.35.0068 is a 32bit app, but it works fine on Windows 7. I haven't had any problems. Perhaps it might be worth trying that also?

Winrar works fine - even the 32 bit version on x64.

I wouldn't do that. In most cases, there are x64 versions of programs, and often the x32 programs will work fine. If neither is the case, there are plenty of other programs that will work as they should.

I've occasionally had issues over the years with antivirus / firewall software hanging up larger downloads while they get scanned. Sometimes this means they end up timed out / incomplete, etc.

If you're *not* using a download manager for them, you may actually want to look into such a thing. At least that way if/when problems arise, you hopefully don't have to re-download the whole thing again.

Sometimes disabling antivirus / firewall for awhile solves the problem by itself, sometimes it doesn't.

guess im gonna try to look into it and look for any package losses,maybe its just the fault of the telekom as always ;-)
i will try a download manager also i think

any suggestions there?

hm... try downloading an archive file bigger than 70mb, but from an P2P application (like torrents maybe) and then see if the archive is corrupted. I'm curious if it's just a browser issue , data packet loss or other problem.

You do use winrar 390 64 bit right?

I think that the current version is 391. I didn't check what changes had been made, but it wouldn't hurt to download and install the new version regardless, just in case the old download file became corrupt before installing it.

I'm havign the same issue, rar and zip files not extracting. I downloaded the Eve online trial and it failed to install due to CRC error. This is a clean install of windows 7 Ultimate 64 bit. I also have issues extracting files I have off my second drive which I use to back up files. They worked perfectly under Windows XP now they are "corrupt".

Any help I would really appreciate it.

Amazeroth I was experiencing this problem too.And since 6 month.i was not able to download any rar or iso files... The problem was not lan card,memory etc... its not a hardware problem.I changed everything.router,wires,pcI spend a LOT OF MONEY...... the problem comes directly from ISP. you may notice that your internet connection slow down and drop some times. CONTCACT UR ISP AND INSIST THAT THE PROBLEM IS FROM THEM.. Good luck dude.
