If only one of several applications requires Win 98, all must use 98 during the same computing session, sí? I think I found the answer to my previous question. From two different dual os how to's:From Guru3d's Dual Boot Guide: You can get lucky and run the same application under both OS’s via one installation point. However many of the larger, more robust applications need dedicated registry settings as well as specific files copied to the \system or \system32 folder. If you are having problems running an application that was installed via another OS, then you should reinstall the app, or run it from the OS it was installed from only.From Dual Boot Blues... Dual Applications for Dual Boot Running a dual-boot system has one more catch: Each OS is on a separate partition and operates unaware of the other, so you need to install applications that you want to use on both OSs twice. Applications can share data and, in most cases, directory structures. Unfortunately, some applications install different executable files for each OS, in which case you have to create separate directory structures. You can't predict which applications will install different executable files, so you need to rely on experience to learn which applications behave this way. You might also have trouble uninstalling an application that the OSs share. The OS from which you first run the uninstall process will delete the executable files and libraries and will remove entries for the application from the OS's Registry database, but the OS won't touch the other OS's Registry. When you dual-boot to the other OS, the uninstall process might fail because the executable file is missing. Then, you need to reinstall the application before you can uninstall it. My approach is to install only the applications that I need on each OS. I use Win2K Pro as my primary OS, so it gets applications such as Microsoft Office. I use Win98 mainly for test work, so it gets only the applications that need testing. I need a few applications such as Dynalink Technologies' Clip'nSave on both OSs, and so far both OSs share one copy. Esteban
