Hi,

I've an SMS Application which runs perfectly in 32-bit OS.

But as my server is 64-bit, I've tried to execute the same application in 64-bit OS, but in vain.

I'm unable to detect where the problem is...Do I need to change the code so as to make the appln run in 64-bit OS?

If so...where to change?

Thanks in advance..

Regards,
Ravi kamesh

Solution 1

You have to set
“Enable 32-bit Applications” to True in IIS app pool

check this.

Solution 2

Hi,

I always suggest people to add logging in the application. that may help you to identify the exact cause of the problem. When application is deployed there is no point of debugging so Logging is the only option to findout error.

Log4Net[^] is really good API for Logging.

As far as this issue is concern, Solution1 may help you.

Hope you find all your future issues from logging.

Thanks

Actully my applicatin is Windows appln in C#4.0 (sry that i've kept asp.net)

So do i need to change in IIS even for a Windows appln?

No, Windows application is not hosted in IIS. so there is no point of changes in IIS.

Also check EventLog. that may help you to find some error message.
