i've created a slipstreamed installation of framework1.1 + sp1....all work propertly but in windows update, only an update is available for me: FRAMEWORK SP1....

there's a registry entry wich fix that problem?

what exactly do you mean? If you have slipstreamed .net 1.1 and the sp1 there should be no items in Windows Update since there already installed.

yes...but windows update saw me there is only an unpdate available: SP1 and the file size is 0kb....

Hi beppemito!

I don't know if this will help you but I had a problem with .Net Framework too.

Windows Update was showing me an update I couldn't install.

That was because I had a registry tweak which disabled rollback.

Search in your reg tweaks file ; if you have something like DisableRollback=dword:0000001, put it to 00000000.

I can't remember where the key is actually located.

Hope this will help.

; Disable Windows Installer Rollback 
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Installer]
"DisableRollback"=dword:00000001

.Net Framework wont install with this tweak activated, I havent seen anyone report this error before but if you have set this tweak, set it to =dword:00000000 and that should fix it, or if your doing it to your cd just delete the tweak.

i've ran regedit but DisableRollback is not present....what must i do?i must create it or not?and where?because in HKEY_CURRENT_USER there isn't MICROSOFT\WINDOWS\INSTALLER.......there is in HKEY_LOCAL_MACHINE!
