I have managed to install this easily enough using the CX6 beta, but after entering my usename and password to authenticate to foldershare, it crashes out with;
Assertion Failed!
Program: C:\Program Files\FolderShare\FolderShare.EXE
File: C:\system\clientCore\connection.c
Line: 1868
Expression: "pConn->state != CONN_FAILED"
Press OK too exit the program, or Cancel to start the Wine debugger.
Pressing OK or cancel simply exits.
