Brothas thank you very much for the help but that's not what I'm looking for Name of our topic is: "How to install LIPSetup.msi file from cmdlines.txt?" We have to conclude that it is not possible to do, right? Instead of WPI I've decided to embed files from LIPSetup in my desired WXP disk on a tricky way. 1) I made a new installation inside VM software and installed LIPSetup.msi after that. 2) I copied all .dll, .cpl and .exe files contained inside LIP and translated them into CAB format as DL_, EX_ etc. It wasn't such a hard job as I expected. Only one thing is still unsolved. Namely, I don't know where to put LIP's html files from %\Windows\Help\MySupport and %\System32\oobe\mui\0c1a Also, dunno what to do with XML files from %\Windows\srchasst\mui\0c1a Exaxtly, I'll have to find WXP english CAB file where the same files are placed and simply replace them.
