Can't start db after install forms

Can't start db after install forms

 

  

OK, I know I did something wrong, but just don't know what. Here is my problem. I had oracle 8i installed in D;\oralce\ora81 directory and then I installed oracle form in D:\oracle\form directory. After install form, I copy tnsname from ora8i to form directory. But m sqlplus won't start from ora81 and I am keeping get message file SP1<lang>.msb not found. What did I do wrong,
many thanks,
