Ok...I think you are right

Lets clean up a litte my post...
I have an A1200 with 1.2GB HDD.HDD has two partitions.One is named WB one is named Leisure.I install the WorkBench 3.1 to WB partition.I am transferring my files from PC to A1200 with null modem cable by AmigaExplorer software.
When i try to transfer WHDLoader user archive files to C: directory under WB partition AmiExp gives I/O error.I can handle this by showing all files.I could transfer WHDLoad drawer to C: directory.
Now on the A1200 side when i press the Install in the WHDLoad drawer it says "Unable to open your tool 'Installer' "
And i noticed that theres a WHDLoader icon in C: directory in WHDLoader drawer.When i try to run this icon WHDLoad screen appears after this screen it says DOS-Error #205(object not found) on loading "WHDLoad.Slave"
After this error on the output window "WHDLoad failed returncode 10" message appers.
For making a try i have downloaded Zool2 install version.I transfer the files via null modem cable to Leusire partition on my HDD.When i try to run Install it says "Unable to open your tool 'Installer' "
I think its more clean now....But i am litte bit hopeless.Please help me because most importent side of a classic amiga is playing games with it for me...
Thanks for your help...
