无法在Win7 64位上安装IIS7和ASP.NET 3.5

Question

Using Win7 32-bit for 3 months and didn't have problem with developing any .NET-based applications including ASP.NET apps.

Just upgraded my laptop's RAM 3 days ago and switched to 64-bit version of Win7.

When I'm working on installing IIS7 and .NET Framework 3.5 SP1, there's an error about not all features were installed for some unknown reason.

When I try to register ASP.NET using aspnet_regiis -ir in c:\\Windows\\Microsft.NET\\Framework64\\v2.0.50727\\ , a dialog box shows with this error message:

"Operation failed with 0x80070643" and after I close the dialog box, another error message on the console command shows with this message: "An error has occurred: 0x80004005 Unspecified error".

I had the same problem and I did everything found on the internet but nothing was useful eventually I was able to solve it by using the following: note: do it on your own risk Add the following to you registry only if the doesn't exist (in my case they didn't exist):

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_2.0.50727]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_2.0.50727\\Names]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_2.0.50727\\Performance] [HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64\\Names]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64\\Performance]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64_2.0.50727]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64_2.0.50727\\Names]

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\ASP.NET_64_2.0.50727\\Performance]

try installing asp.net 64 bit after that

Answer 2

Configure IIS to run in 32 bit mode (assuming your apps are 32 bit mode, since that's what you originally developed on).

Try running aspnet_regiis after that is done. Use the 32 bit version of aspnet_regiis.

I know this is a fairly old post, but I thought I'd share what I did to solve this problem on my machine running Windows 7 64-bit.

While IIS was installed on my computer, the ASP.NET features were not enabled.
To enable ASP.NET do the following:

Navigate to the Turn Windows features on or off dialog. It's located under
Control Panel --> Programs and Features .
Note: Typing 'features' in the Start Menu search will also get you there.

When the Turn Windows features on or off dialog appears, navigate to
World Wide Web Services --> Application Development Features
and make sure ASP.NET is checked.

Once this was done the aspnet_regiis -ir command worked perfectly and I could run and debug ASP.NET apps on my machine. Hope this helps.

set IIS to run in 32 bit mode

http://learn.iis.net/page.aspx/201/32-bit-mode-worker-processes/

Try running aspnet_regiis after that is done. Use the 32 bit version of aspnet_regiis.
