I am running Vista Business on a Thinkpad T61p with 3 gb ram and 72 gb of free space.

When attempting to install some new software purchased on CD, I immediately get the following dialog box & error message:

Setup.exe – bad image
C:\windows\system32\LZ32.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

Aha! It must be a faulty disk! Nope, my husband was able to install it just fine on his Windows XP system.

I contacted the software vendor. Since my husband was able to install it on his machine, and they’ve never seen this error message before, they believe it is a Vista problem.

Since Lenovo doesn’t provide software support (Buyer Beware!), I visited the thinkpads.com forums and posted my issue there http://forum.thinkpads.com/viewtopic.php?f=38&t=74974

I discovered that I had malware in the form of 5 BHO registry keys. I ran Malwarebytes' Anti-Malware and Hijack This and the system seems to be clean now.

I’ve downloaded a LZ32.DLL file (with an earlier date – will that be a problem?), hoping to replace the corrupt file. Nothing I’ve done to change the security permissions will allow me to do that. (Booting in safe mode, running as administrator, changing the permissions to full control – I still get “Unable to save permission changes” error messages.) I can’t rename or replace the corrupt file. (I can, however, place a copy of it on my desktop and rename it there.)

Is LZ32.DLL a Windows Vista file? Should I be able to extract/copy it off the Lenovo Operating System Recovery Disc? I don’t see it in the list of files.

Is there a way to just repair this one file, rather than fiddling with the entire OS through the various Vista Repair and Recovery Tools? I read through that section and didn’t see anything that seemed relevant for this particular problem, but I could have overlooked something. I haven’t tried System Restore, because I don’t know when I acquired the BHOs and don’t want to restore them.

Another website says LZ32.DLL has to do with displaying ttf files. Is that true?

Should I “shred” the original apparently corrupt LZ32.DLL file using Malwarebytes' Anti-Malware and move the downloaded file into the system 32 folder and hope it works?

My computer is working fine otherwise, so I don’t want to screw it up trying to fix this. But since I spent a good bit of money on this software, I’d really like to be able to use it.

Thanks much for your advice – it is greatly appreciated!

lz32.dll is a process belonging to the LZ Expand/Compress program . lz32.dll contains libraries for LZ Expand/compress


lz32.dll is not a critical component.
