Unable to install IIS7 and ASP.NET 3.5 on Win7 64-bit

Question

Using Win7 32-bit for 3 months and there were no problems developing .NET applications, including ASP.NET applications.

I just updated my laptop RAM 3 days ago and switched to the 64-bit version of Win7.

When I work on installing IIS7 and the .NET Framework 3.5 Service Pack 1 (SP1), an error for some functions was not installed for an unknown reason.

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

"The operation failed with 0x80070643," and after closing the dialog box, another error message appears in the console command: "An error occurred: 0x80004005 Unspecified error."

Answer 1

I had the same problem, and I did everything on the Internet, but nothing was useful, in the end I was able to solve this problem using the following: note: do this at your own risk and add only the following to the registry: if it doesn’t exists (in my case they do not exist):

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

[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ ASP.NET_2.0.50727 \ Items]

[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 \ Items]

[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\]

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

asp.net 64

aspnet_regiis . 32- aspnet_regiis.

IIS , ASP.NET .
ASP.NET, :

Windows..

. "" "" "".

Windows /,

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

Answer 4

configure IIS to 32-bit mode

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

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