Just tried to download the lastest update (SU 7.1)
The file downloads ok, but when I go to run it. The install fails, and says Extraction failed file is corrupt
After some research on the net. I decided to try and use firefox instead of Win Explorer to download the file. I didnt have firefox installed on this computer. So I downloaded it, pressed run and the same message pops up.
Has anyone else had the same problem.
The SketchUp installer is a self-extracting executable. It has a small amount of built-in checking to prove whether the extraction is completed properly. If it says there was a problem, that means during the process of downloading, some of the bits being sent from Google's download servers to your machine became corrupted. The only thing you can do is download it again from scratch and see if you have better luck the next time.
One option for ensuring the file is OK is to check its MD5 hash. If someone authoritative tells you what the MD5 should be, then you can run a program that performs a mathematical check on the file and produces a hash as output, which you can compare to the value you expect. If the value matches, your file is good. If the value does not match, you need to delete the download and try again.
I expect you're downloading Google SketchUp Pro 7.1 for Windows:http://dl.google.com/sketchup/GoogleSketchUpProWEN.exe
The MD5 hash for that file is:
If you get a free MD5 checker for Windows, you can run it on the file you download and see if you get the same string as above. If not, your file is corrupted and you need to re-download.
I've never tried the following MD5 programs, but they both look reasonable:http://www.softpedia.com/get/System/File-Management/MD5-Checker.shtmlhttp://www.softpedia.com/get/Security/Security-Related/WinMD5Free.shtml
I hope this helps.
