Hi, has anyone practical experiences with RS 5.11 or 5.12 based in windows 64-bit operating systems like XP 64-bit or vista business 64-bit ? In the release notes i can read: **_Note:_** _RobotStudio 5.12 does not support 64-bit editions of Windows XP Professional or Vista Business or Enterprise_ But: What does this mean ? - Is the software working (without the benefits of 64-bit), or not ? Are there problems and limitations, or not ? Please tell me your experiences. Thanks to all. Klaus ---

Hi Klaus, We can not guarantee that RS will work correct with 64-bit OS. You may run into problem, specially with the Virtual Controller. Therefore are we not recommending 64-bit OS when you run RobotStudio. ---

Hi Anders, thank you for your hints. - That is what i have expectetd. But i want to know, if there are any experiences with it.

Anders, are there any plans for Vista64bit support? Dean. ---

I have installed it on Vista Ultimate 64 bit without any problems, I used the 30 day trial on my home computer without any problems as it was faster than my work laptop. I did have a couple of Virtual Controller crashes, but i get plenty of those running 32 bit anyway so I didnt see any extra problems because it was 64 bit (and having 8gb memory certinaly helped) ---

Anders, What problems exist on the VC specifically? I recently upgraded to Windows 7 64-bit and can’t seem to get a PCSDK application to work…I keep getting an error related to the ABB.Robotics.Adapters.IRC5 assembly: “Could not load file or assembly ‘ABB.Robotics.Adapters.IRC5’” when doing a “new NetworkScanner()”. ---

Hi Dan, A .NET application will run in 64-bit mode by default, but the PCSDK only supports 32-bit operation. Therefore you must change the build settings of the .exe to target 32-bit only: Alternatively, if you can’t recompile the app: [http://blogs.intesoft.net/post/2007/12/Running-NET-Apps-in-32-bit-mode-on-64-bit-Windows.aspx](http://blogs.intesoft.net/post/2007/12/Running-NET-Apps-in-32-bit-mode-on-64-bit-Windows.aspx) regards, Johannes
