Hi,

I have been told to place a pointer question here.

My question is at this link: (500 points, urgent)
http://www.experts-exchange.com/Applications/CRM/Q_21805825.html#16410042

What I need to know, is if it's really true that the following error message from MS CRM 3.0 when you have created a callout:
The format of the file <myFile>.dll is invalid
really is caused because I use VS2005 to compile, and not VS2003. I've read that you have to write/compile in .NET Framework 1.1. Is there a way to do that when VS2005 is installed? I've searched settings in VS2005 to choose which Framework to compile in...

I can't get VS2003 installed on any of my VS2005-computers. I get the message about that another application has asked for a reboot every time I start the installation (nr 1, Prerequisites or something, my poor English apologies...).

Please add all comments there, and not here...


Best regards,
BITK :)

VS 2005 doesn't have option to compile for .NET Framework 1.1.
Different VS versions can exist on the same computer, but new version must be installed later. Try to uninstall 2005 version, then install 2003 and 2005.

Thanks for the tip...

I haven't got time to test it yet, but I give you the points for this question here. I thought of this, but it's nice to know before I start on this... :)


Best regards,

Oops, I missed your "add all comments there, and not here". Usually links are posted with 20 and not 500 points.
I worked some time with VC++ 6.0, 2003 and 2005 Beta Express on the same computer, I hope this will work for you as well.

No big deal for me - I give points when I get a good solution. ;)

PS! I've tried to install VS2003 on a computer WITHOUT VS at all... And only Framework 1.1 is installed there. Win XP... I just can't get it installed there. I'm getting this message while clicking the "Prerequisites" (task 1 of the installation...) about that another program has wished for a reboot... It happens after reboot, too... What can I do?


Best regards,
BITK :)
