I'm having problems installing the software on my Vista pc

[KB]

If, when installing SellerDeck ecommerce software onto a Vista pc, you get the error:

1: ALLUSERS property is not 1 - this MSM cannot be used for a per-user or fallback-to-per-user install

then you need to uninstall the version of .NET framework and install a more up-to-date version. You can download the version that you require from here.

There is some background information regarding this error here.
