I just remembered something with the last "clean install" for XP and LO. This was for 3.4.1[or 3.4.2?] and XP.
I had to install LO twice in a row, WITH NO uninstall in between. I do not know why that happened, but it happened to me twice. BUT, the last time I installed 3.4.4, or was it 3.4.5, on XP/pro I did not have any issues. There was just something in the XP system[s] I was dealing with that had issues and not all of what was to be installed was installed properly. The second install, which was a "repair" finished the install properly. I do not know if it was a problem for XP or for LO or a combination of both, but the second install [without an uninstall] fixed the problem and it worked great from there on and the installing for the next version[s] worked fine.
I really prefer people try the most stable version of LO, which currently is 3.4.6, before they go to the most cutting edge version, which currently is 3.5.2.
I have found that 3.4.6 works very well for me on Win XP/pro, Vista, and Ubuntu 10.04/12.04. There are some issues in 3.5.x that is in their bug list that need to be fixed before I go to 3.5.x over 3.4.6..
AS FOR not installing if the install file was bad or incomplete, that is not true. I have had both type of issues try to install and then fail somewhere along the way. Usually it fails so bad that I have to do a lot of cleaning up my system after the failure.
Right now, I have a HP Pavilion zv6123 laptop running XP/pro [32-bit] and it has LO 3.4.6 running on it. I have to check what service pack is on it, but the package installed fine.
