Error 1709 when install .Net framework 1.1

Error 1709 is that Microsoft installer is not registered.

“msiexec.exe /regserver” should fix that.

    This is usually caused by an install getting stuck.

    Although doing that will fix it 99% of the time, if it doesn’t it’s probably not staying fixed long enough and you’ll have to clear out a few registry keys in HKEY_CLASSES_ROOTinstallerproducts – but be careful as always when editing the registry. Aim for the last thing installed as this is most likely the source of the problem.

    I’ve mostly seen this when badly designed installs are run using active directory.
