You can avoid having DHE mess up your other programs by installing it into a separate wineprefix. First create it: Code: WINEPREFIX="/home/user/DHE" wineboot (substitute your username for "user") Then use winetricks to install dcom98 to that wineprefix: Code: wget http://www.kegel.com/wine/winetricks env WINEPREFIX="/home/user/DHE" sh winetricks dcom98 After that cd to the directory where you've extracted the DHE installer, and install it to the new wineprefix: Code: env WINEPREFIX="/home/user/DHE" wine DHWE42.exe Every time you run DHE, you will have to specify the wineprefix: Code: env WINEPREFIX="/home/user/DHE" wine "C:\Program Files\Dynamic HTML Editor 4x\DHWE.exe" You can specify the wineprefix in your menu editor so you don't have to type all this out in the console every time you want to run the program. You can use this procedure to set up as many different wineprefixes as you want; just substitute the actual filenames & paths for the program you want to install. If you like to experiment, using a separate wineprefix for things you are testing will help you avoid messing up your other programs.
