Trouble Installing NinjaTrader on Vista (assembly policy 8.0 vc80 crt)

[dallastrader]

I was interested in trying out NinjaTrader with an Ameritrade data feed and tried to install it on my Windows VISTA pc but got this error message:


An error occurred during the installation of assembly 'policy.8.0.Microsoft.VC80.crt type="win32-policy", version="8.0.50727.42" publickeytoken= "1fc8b3b9a1e18e3b", processorArchitecture="x86". Please refer to help and support for more information.

Does anyone know what I should do or if I can install it?




thank you!

I searched the forum and found a response to check if dotnetframework was installed.

I put %systemroot%\Microsoft.NET\Framework in my browser like microsoft states, and verified all versions of framework are installed.

Hello,

Thank you for your post.

Can you please reinstall the .NET framework.

Please follow the instructions below to re-install the Microsoft .NET Framework on your PC.

Terminate any applications running on your PC
Go to the Windows Control Panel
"Add/Remove programs" for XP users or "Uninstall a program" for Vista users
Locate and uninstall the .NET Framework
If your highest version is 4.0 or greater than do not continue with these instructions and let us know and we will follow up with further instructions
If your highest version is 3.5 then proceed and uninstall this version and skip the next line
If your highest version is 2.0 then proceed and uninstall this version
Install version 3.5 of the .NET Framework which contains the 2.0 version which is required by NinjaTrader 6.5 (Download from here (http://www.microsoft.com/downloads/details.aspx?FamilyId=333325FD-AE52-4E35-B531-508D977D32A6&displaylang=en))
After the install please check for updates to the .Net Framework with the Windows Update function Note: Do not reboot your PC in between these steps as this can potentially create more issues that we are unfortunately not qualified to assist with.

I did the uninstall and clicked that link and installed it and it still gives me that same error message. I tried it from explorer and then firefox. Tried running it to install and tried saving it and then installing. Nothing seems to work, keep getting that error. :(

Hello,

Can you please do a complete uninstall, which includes clearing the browser cache.

Please follow the steps listed below to completely uninstall and reinstall NinjaTrader:

Close all running applications.
Then from the Start menu select --> Control Panel --> Add and Remove Programs.
From Add and Remove Programs select NinjaTrader 6.5 and click Remove.
Then manually delete the folder "NinjaTrader 6.5" located under Start --> My Documents.
Delete any NinjaTrader installation files. This can be done by going to Start --> My Computer --> Search button --> search for (NinjaTrader*) --> select Local C Disk and then press search.
Then you will need to clear your internet browser cache and history. You will clear this from within your internet browser (with IE, Tools-->Options, delete cookies and files, clear history).
