Setup Project does not recompile after Modification

Hi,

I have to change in my setup project. After this I want to recompile it. But there are 2 types of error I face.

1) relating "Hresult = 800000a"  & the file is .vdproj

2) relating "can't update the dependency" & the file is .vdproj

I have only 1 .vdproj file. 

I have tried hotfix but can't solve the problem.  Need your help. Thanks.
