Hi,

OpenSession Error 50

How can i fix this problem to keep try this COM component ?

Best Regards

The complete error message should say "OpenSession Error 50 - Distributed service error." in some cases following by additional diagnostic information.

You can turn on the tracing flag in the OpenSession to get the trace of communication calls. Please let us know what you get in the trace.

You forgot to specify the server computer name for the ServerLocation parameter. If 24x7 runs on the same computer either specify real computer name or it's IP address or specify LocalHost. Don't leave the ServerLocation parameter empty.

Hi,

I specify the server computer name in ServerLocation parameter, and the problem dont fix. The same erros still happened, and now open a notepad document (licence.txt) in the same time when de erros is appears.

Have any ideia ?

Popping up notepad window with the license.txt occurs only if a license violation is detected. Running 24x7 COM or 24x7 Java interface requires a separate license and license key. Using the same key leads to the connection being denied.

Running it on a web server requires a site license.

How can i find price list of this COM product, i try to see in site but i dont find any information about. Is it possible to test a trial version of this product ?????

The price differs for different versions. Site license price for version 3 is $3900. Single installation license price for version 3 is $270. It is $3600 and $240 for version 2 respectively.

To play with a trial version use your registry editor to create "HKEY_LOCAL_MACHINE\SOFTWARE\SoftTree Technologies, Inc.\24x7 Scheduler\3.0\RC" key. Under that key create new string value "Serial" and enter 00000-00000 for the value.

If you use version 2 replace 3.0 with 2.0 in the key name.
