and then

The meaty one is a bit too big apparently.... though probably contains the problem somewhere hah.

Thanks greatly in advance for the assistance, I'm really disliking generic error codes right now.

Prior to installing AppFabric, the groups AS_Observers and AS_Administrators must not exist. To check if they exist for you and to get rid of the that you just go into administrative tools, computer management, local users and groups, and groups and if AS_Observers or AS_Administrators exists, delete it. as shown here msdn.microsoft.com/en-us/library/ff637696(v=azure.10).aspx Hope this helps out anyone who encounters this problem. This resolved the problem for me and the program is finally installed haha
