5b just shows up in the run box. Here is the error message

Unable to create an instance of the Ascom PlatformInstaller.CustomActions installer type--Exception has been thrown by the target of an invocation.--Creating an instance of the COM component with (EDEBAAF9-E097- 4D30-AA5F-6A4B0F17-DC6D) from the IClassFactory failed due to the following error 800a01ad.

There is not enough information here for anyone to help you. At the very minimum, we need the full text of the error message (preferably a screen shot). Please see my blog article on how to report a bug at community.tigranetworks.co.uk/blogs/tim_long/… – Tim Long♦ Feb 28 at 23:23
Also, are you absolutely certain you're installing 5.0b and not 5.0a? – Tim Long♦ Feb 28 at 23:24
For other readers, 5.0b is the same as 5.0a except for an installer change. If you have 5.0a, leave it be! – Bob Denny♦ Mar 4 at 21:23
The GUID is the Class-ID of the DriverHelper.Profile COM object (the gateway from COM into .NET for Platform 5.5). It appears that the installer/MSI's CustomAction is failing in the constructor, which is trying to create an instance of DriverHelper.Profile. I have no idea how to troubleshoot this, as MSI installers are a mystery to me. – Bob Denny♦ Mar 4 at 21:39
Not that MS KB articles always help that much: support.microsoft.com/kb/194801 The DLL referenced by the GUID on my machine is: C:\Program Files\Common Files\ASCOM\Helper.dll Need to ask: what version of .NET do you have installed? – lynol1000 Mar 6 at 16:46

Me too got the same error "Unable to create an instance of the Ascom PlatformInstaller.CustomActions installer type.....error 800a01ad" installing the 5.0a version; the same with version 5.0b. I tryed to reinstall the .net framework, even version 2 and version 3.5 but no change were. I verifyed by a checker tool that the .net framework is correctly installed and working. I'm using windows XP SP2 but with one particularity: for some reason the operating system is not installed on drive C: but on drive D: I saw that because the above behaviour sounds to me as if the installer was looking for some needed component on RIGID PATH (i.e. "C:\program files", or similar) and not in the real machine paths. I hope this information could help somebody that has inside view to solve this bug.

The OS being installed on drive D: may be significant so I've highlighted it. – Chris Rowland♦ Jun 13 at 15:52

I get the same problem, first trying to run the 5.5 update and then trying to uninstall 5.0 to reinstall as seemed corrupted by failed 5.5 update.

Running .net framework 3.5, Win XP SP3 build 2600
