Does anyone meet the same problem? I finish downloading and it show installation failed.... T^T

Check the file integrity. I have to re-download all 6 parts because my internet sucks and cut out over night. :c

I have downloaded it a lot of times..... None of them works... T^T+

Installation fails for me too via gog galaxy, it's struck in "waiting for relase", even if i downloaded the day1 patch. At the end of the download it says "installation failed", but i dont know why. i cant even check for files integrity

I have been getting this problem when I try to install:

Installation failed with code: -3: Checksum error
Please restart the installer and try again
If the problem persists, please contact Support

I don't want to redownload because the download is huge and australian internet is slow, not to mention it would use up my purchased internet download amount effectively costing my money. Since I manually download the 7 parts right from the site I was hoping to identify the problem file and just redownload that.

I used this site's how to to run a checksum: pcsupport.about.com/od/software-tools/ht/verify-file-integrity.htm
Using the -sha for the end (not that I know what any of this means)

I have the numbers but I have nothing to compare them to. Would someone whose installation worked fine consider running a check and posting the numbers for those with errors to compare to?

Mine just keeps patching to like 20%... then saying 'failed', then starting over again. All the while saying 'waiting for release'.
