Hi, one last thing, since I already installed some machines using the package definition and altered it now to use a batch file for the remove task, will it be sufficient to increase the version number of the package to get the remove information updated on the already installed clients? Thanks in advance, Stefan Pendl Stefan wrote: Hi Rainer, so if one uses batch files to choose the correct installer he has to use them for the other tasks too. Thanks for the info. BTW, I noticed that your install batch file has a spelling error in the custom installer procedure it set the exit code to ERRORLEEL (missing V) ;-) --- Stefan ---snip |
