cant connect to oracle

[derik82]

Hi all!

I have a connection problem. I am using a 64bit Windows XP.
I installed a 32bit oracle client (tried 10gr2 and 11 also).
But cant connect to the oracle server with pl/sql developer.
I use the right tnsnames.ora file. the firewall is disabled. I can connect with sqlplus.
the pl/sql developer throws this error: 'ORA-12154:TNS:could not resolve the connect identifier specified'

please help,
thanks

Thanks I have found the solution in previous topics.
It helps when you reinstall the plsql-developer into folder without parentheses.

bye
