WPI 4.5 Error after upgrading

问题

I just upgraded Web Platform Installer to version 4.5 on two separate Windows 8 machines. (One is a physical machine and the other is a VM). I am unable to run WPI 4.5, both are showing the following same error:

An error occurred while parsing EntityName. Line 42134, position 81.

Update: Confirmed it was an error with the product list from Microsoft. Found this log file entry:

回答1:

I'm really glad Google pointed me to this question. I got the same error literally 2 minutes after you posted this question...

It seems to have been a Microsoft server-side error, as it has corrected itself for me since I started typing this answer.

Had the same error. Uninstalled WPI, reboot and reinstalled. Now the only error I got was not being able to load a feed.

But it did startup and is usable.
