the manifest may not be valid or the file could not be opened

I want to install outlook add-ins (Which is developed by Visual studio 2008) but I've got following error.

Name: From: file:///D:/Project/.Net Learning/OutlookAddIn3/OutlookAddIn3/bin/Debug/app.publish/OutlookAddIn3.vsto

Exception reading manifest from file:///D:/Project/.Net%20Learning/OutlookAddIn3/OutlookAddIn3/bin/Debug/app.publish/OutlookAddIn3.vsto: the manifest may not be valid or the file could not be opened.

I know this is super old, thought I'd share. This is what fixed it for me:

The short of it is my Installation folder URL was wrong.

Probably your windows registered name have a special character like "*". I suggested to you change windows registered name. you can change it from registry in (Win XP):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

change value of these keys: RegisteredOrganization RegisteredOwner
