Wine 1.7.0 console output - Fail 1st run then success 2nd

dotnet20sp1 installer fails most of the time (around 2/3) in Wine 1.7.0

1. winetricks dotnet20
2. wine /mnt/winetricks/dotnet20sp1/NetFx20SP1_x86.exe /q

err:msi:ITERATE_Actions Execution halted, action
L"DD_CA_ScheduleNgenServiceVersionCheck_X86.3643236F_FC70_11D3_A536_0090278A1BB8"
returned 1603

Run the installer 2 to 4 times and it will complete successfully. dotnet
verifier confirms.

Setting win2k mode (winetricks dotnet20sp1) makes no difference.

This is a recent regression.

Reverting this commit in Wine 1.7.0 fixes the problem. (There are other
problems with the installer but it completes).

Note: Affects winetricks dotnet20sp1 verb.
