Lightroom 3.2 Installation Problem on Windows 7 64-bit


I can't install Lightroom 3.2 (German) on my computer (Windows 7 Professional 64-bit).

While copying the extracted program files the following error message appears:


An error occurred during the installation of assembly component {6435B7C0-E0C8-3EA2-91AE-7640034EAFCE}. HRESULT: 0x80070002.


I found out that other users had the same problem, and couldn't find a solution.

Perhaps it is a Microsoft .NET Framework related problem. But after installing .NET Framework 4 nothing changed.


Thanks for ideas to solve the problem.

    First, I would download the latest 3.4.1 version and then try to install this version.

    Go here:


    Then, make sure you run it with administrative credentials (right click, run as administrator).


    Post back if the issue persists.

    Hmmm .. some users reported problems when they where not the owner of the folders involved. I would also try to deactivate the anti-virus scanner and run from a local drive - just further ideas. Try to reinstall .NET, but not only version 4 as you already did. I'd also try to reinstall 3.0 and 3.5. I'm kinda running out of ideas ..

    I am running LR 3.4.1 64-Bit on W7 64-Bit myself - OS language German and LR varying German or English.
