Hi, I have installed Calibre using wine 1.3.22 . The program is not usable since adding/converting ebooks is not working. Running wine calibre-debug -g I get the following error: Exception in thread Thread-4: Traceback (most recent call last): File "threading.py", line 530, in __bootstrap_inner File "site-packages\calibre\utils\ipc\server.py", line 221, in run File "site-packages\calibre\utils\ipc\server.py", line 139, in launch_worker CriticalError: Failed to launch worker process: Traceback (most recent call last): File "site-packages\calibre\utils\ipc\server.py", line 149, in do_launch File "multiprocessing\connection.py", line 121, in accept File "multiprocessing\connection.py", line 373, in deliver_challenge IOError: [Errno 233] Pipe not connected It seems to me a bug with python. Firstly, I installed Python 2.7 and then 3.2... Still the same problem. I even deleted the wine directory and i installed calibre WITHOUT python and I still get the same error!!!!!!!! Does wine have python builtin... does it use the linux version? Wine output is the following: fixme:system:SetProcessDPIAware stub! Starting up... fixme:win:FlashWindowEx 0x33c270 fixme:ntdll:NtLockFile I/O completion on lock not implemented yet fixme:win:FlashWindowEx 0x33bf98 fixme:imm:NotifyIME IMC_SETCANDIDATEPOS fixme:imm:ImmReleaseContext (0x20078, 0x16e8a0): stub Started up in 1.20499992371 fixme:win:FlashWindowEx 0x33c030 fixme:win:FlashWindowEx 0x339588 Exception in thread Thread-4: Traceback (most recent call last): File "threading.py", line 530, in __bootstrap_inner File "site-packages\calibre\utils\ipc\server.py", line 221, in run File "site-packages\calibre\utils\ipc\server.py", line 139, in launch_worker CriticalError: Failed to launch worker process: Traceback (most recent call last): File "site-packages\calibre\utils\ipc\server.py", line 149, in do_launch File "multiprocessing\connection.py", line 121, in accept File "multiprocessing\connection.py", line 373, in deliver_challenge IOError: [Errno 233] Pipe not connected Any help is appreciated, Thanks A
