I installed MCEBuddy 2.2.14 on an XP system running MCE2005. The installation process installed the .NET 4 Framework Client automatically.
There is a known issue (

Uninstalling MCEBuddy did not resolve. I had to manually remove the .Net 4 Client using add/remove programs.
Your software should detect this issue before installing and abort the installation.
A clean uninstall would remove .NET 4 Client if yours is the only registered application requiring it; I should not have had to manually remove that client.
Thanks.
