Error copying file lexmark to dimension

Help, tried everything (maybe)

I bought a used Dell dimension and my lexmark Z705 will not install the software. Message is LXBLDR5C.DLL, error copying file. I have tried multiple times with the CD (worked on my other computer) and downloaded the software from Lexmark. Always get the same message. I did a full system scan with Norton. Software loads but does not copy to the drive. Any help would be appreciated.

Thanks,
