Running Asp.Net 1.1 and 2.0 together in Windows 64-bit environment

leave a comment »

To be noted, Microsoft is not going to release 64-bit version of .Net framework 1.1. So installing it on Windows 2003 64-bit OS will require it to run in “32-bit mode”. Normally this is done easily when you try to install FW 1.1 on OS it will ask you to run a command during installation and that enables IIS to run FW 1.1 in 32-bit mode.

Asp.Net Tab in IIS MMC will be missing so assigning different FW version to different websites should be done using command line tool : aspnet_regiis.exe (it is separate for each FW version and can be found in framework directory e.g. C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322)

Examples:
aspnet_regiis.exe -s W3SVC/1/ROOT/<yourappname>       (for recursive update)
aspnet_regiis.exe -sn W3SVC/1/ROOT/<yourappname>     (for non-recursive update)
