I had LibreOffice 3.3.2 installed on Windows 7, and just upgraded to 3.4.2rc1 (both in french). Now when I double-click the LibreOffice icon on the desktop, I get an error that it cannot find comphelpMSC.dll. I checked the md5sum of the installer, and it's correct.
I just installed 3.4.1, and this version is working fine.
Maybe you wanna reload the package from another source (torrent). My copy of LO 3.4.2 RC1 works just fine under Win2K.

(In reply to comment #3) > Resolving as WORKSFORME per comment 1 Comment 1 was about 3.4.1, not 3.4.2rc1. Anyway, I tried again with 3.4.3, and things are working fine again.
