We have an install that worked here perfectly on all of our machines but was failing for 1 customer in the field with a Decompression error #8 when trying to decompress a quickbooks installer in our installation.
We assumed it was a bad download. The end user downloaded 5 times and it failed everytime. then our tech support dialed in and downloaded and it failed twice.
Finally we found that the end users system was running Avast antivirus. We shut it down, redownloaded and the install worked instantly. It is as if the anti-virus was preventing either A) the entire download from being received or B) the decompression of the qbooks installation file.
Hope this helps someone.
