Hi, I am a new member, just joined this evening but hace been playing with PTE since 2003. Early in 2009 my PC crashed and I decided to rebuild but had a number of disasters with external drives which have only recently been resolved and during the last two weeks my newly built PC is actually running. I have a clean installation and am running Windows 7 Ultimate, 32bit. My problem is that I cannot re-install PTE 5.5 De Lux or earlier versions which were in zipped folders and copied accross from my old HDD. When I click on setup in any version either a window opens inviting me to extract all files and when I do I get an error message 0x80004005 or, alternatively when I click on setup a window appears containing the following message: "Compressed (zipped) Folders Error. Windows cannot complete the extraction. The destination file could not be created". The latter message applies particularly to v.5.5. After trying for sometime to activate the older versions I decided to try downloading PTE 6.0 but when I tried to use my Key I received a message telling me it was for a different product. Neither my original Key nor that for v.5.5 would work, the same message was received for both. During the time my PC has been out of action I feel certain that my Licence for V.5.5 should have been renewed but I would still have expected it to run with limited facilities. I have sent a message to WnSoft and am awaiting their response but would be interested to know if anyone else has experienced similar problems or has an answer to it. During 2009 I bought a MacPro running Snow Leopard and am looking forward to the advent of PTE for Macs.
