After checking the prerequisites, the setup throws the message:"This program is blocked due to compatibility issues"Program: Windows Server Update ServicesLocation: m:\43....c4\WusSetup.exeChecking for some online solution, does not help. If I cancel the setup shows 0 Total 0 Passed. It allows me to continue with the setup but the serial key fails.The serial key problem looks to be more a 'checking requisits' problem. How can I solve my problem with WusSetup?I have removed the WUS as a role because of this.Thank youAdelinoAdelino Araujo

Hi,Does WSUS exist before SCE installation? If possible, try to unistall WSUS first. Checked for the registry key (HKLM\Softwares\Microsoft\Microsoft Operations Manager). If it exists, deleted the registry keys. Also, check if the <SCE servername>_MG is there in ADUC. If so, please also delete it.After that, try to download the new installer from the following link and then re-launch the installation.http://www.microsoft.com/downloads/details.aspx?FamilyID=246df207-f051-47c3-bd64-c9072281c3c8&DisplayLang=enHTH.Jie-Feng Ren - MSFT

Thank you for the reply.I have done the install process with and withou WSUS. I have removed again and checked there registry keys. They did not existe. Also in ADUC none object exists with that name.Im downloading it again from the link and I have a question, since I have Windows 2008 x64... Supported Operating Systems: Windows Server 2003 R2 Enterprise Edition (32-Bit x86); Windows Server 2003 R2 Standard Edition (32-bit x86)Is it only possible to install on x32? My system is 64 bit...Thank you very mutch for your time.Adelino UPDATE- the install works well; my copy on CD does not! that was downloaded from Microsoft on my MAPS subscription! Maybe it is some cd error... I guess!- the part on the SQL check said that it cannot find sql server 2005... I had it installed before... but this is another problem! Adelino Araujo

Hi, Only SCE sp1 is supported to install on Windows Server 2008. Also, since the platform is Windows Server 2008 X64, You need to install X64 SQL SRS sp2 or above locally.
