Error: "Cannot access a closed file" Just for zip coming from 64bit

Nov 22, 2011 at 11:46 AM


when i try to call from a ZipEntry .OpenReader or .Extract, i get the error "Cannot access a closed file" , i made some test and the same zip file can be read normally if its made in a 32bit machine, but i get the error above if comes from 64bit. 

Am i doing something wrong? can i solve in some way?
