Due to a move into oracle database, my company upgrade their odbc client from centura 3.5 to centura 3.6. Unfortunuately, we came with an issue. Those who had centura 3.5 before cannot connect to the oracle database but the new pcs with a fresh 3.6 driver install are ok. We suspect a confict in the two versions but how can we remove the 3.5 driver completely? In another site i found that i have to format the pcs and put the new 3.6 driver. Is there another way of removing the old 3.5 centura driver without formatting the pcs?
