Install vs. Net on both operating systems in the same path

Recently redo the system. a c-drive WINXP professional is used for Internet access and daily development, and another D-drive win2k3 server is used for research. NET Enterprise Servers. Visual Studio is installed on both operating systems. NET Enterprise developer 2003, hard disk is not big, need to install two copies. net is really not willing to that 2g space, haha, first install in WINXP, the installation path is put in E: \ Program Files \ Microsoft Visual Studio.. NET 2003, and then install it under win2k3. The installation path is the same. A prompt is displayed, indicating that the installation is successful! Haha, there is not much change in the space of the e-disk (only about a hundred megabytes of changes, which may be caused by different operating systems), which is good and saves a lot of space.
Try to use vs. Net in win2k3 to create a winform Application ProgramThe prompt "VC software package is unavailable or not registered", I Kao, I have long guessed that there may be problems, really yes, dizzy! Try vs. Net in WINXP. No problem. Check it. If it turns out to be. net installer finds some TLB files and DLL files already exist, so they will not be registered in the computer again. In most cases, the earlier version of Visual Studio. net is prone to this error, especially when the old version is installed on another operating system. It seems that this is the reason. What should I do? Instead of letting me uninstall it, it will delete E: \ Program Files \ Microsoft Visual Studio. NET 2003 all files, I connected to. net cannot be used. Isn't it because the chicken is not a zombie? Let's fix it. Open "Add/delete programs" under win2k3 and select. net "change/Delete", select "repair/reinstall" according to the interface prompt. After a long wait, the repair is completed. Create a winform program, OK! It turns out that the repair program is forced to register some items that are not registered in the installation program.
