Market cache import troubleshooting
The things to do when cache import doesn’t work
- Read the list of issues and solutions below
- Ensure the tab Market data is active on Market window in EVE Online
- Check the cache import preferences carefully: you should enter absolute path to your EVE Online client
- Ensure that you don’t launch EVE Mentat from path with non-latin symbols
- Check the location of EVE Mentat: tool should not be located in system protected folders (c:\Windows, c:\Program Files, etc).
- Make sure that you don’t ever launch your client with -lua:off command line parameter. Then look for cache folder inside EVE Online client folder and delete it.
- Clear EVE Online cache
- Shut down client, find it’s cache folder and delete MachoNet sub-folder
Issues and solutions
EVE Mentat reports “Error calling cache import tool. Code: 255” on cache import attempt
Solutions:
- Check the location of EVE Mentat: tool should not be located in system protected folders (c:\Windows, c:\Program Files, etc).
- Clear EVE Online cache.
- Make sure that you don’t ever launch your client with -lua:off command line parameter. Then look for cache folder inside EVE Online client folder and delete it.
- Find and delete manually MachoNet folder. Usually it is located here – C:\Users\UserName\AppData\Local\CCP\EVE\your_eve_client_location\cache\MachoNet.
Otherwise write a bug report with log.txt file attached.




Is it possible to set cache location manualy? i use a network with different computers, so automatic detection seems not to work for me
No, but it will be implemented in the next update.
Is it possible to use Eve cache folders on mapped network drives to access caches on other machines?
I have tried this and get the 255 error, while the local cache works fine.
@blackhuey
I hope it will be possible when direct cache location feature is ready.
[error] Updating market orders (cache)…

@Trinity Cipher
Try to install Microsoft Visual C++ 2008 SP1 Redistributable Package
This isn’t really a ‘fix’. Basically, after any sizable amount of cache files are built up, I have to delete my machonet folder in order to get rid of the ‘error calling cache import tool’ error. If I have to delete my cache in order to import it EVERY time cache files get numerous, I can’t really ever import my cache now can I?
@Derek
The latest release of EVE Mentat contains all fixes for cache import tool.
If you already use latest version please post a bug report (with logs of course).
EVE Mentat don’t import cache files. When I make import it say “[ok] Updating market orders (cache)…
[info] Importing from client at ‘C:\Users\user\AppData\Local\CCP\EVE\c_progra~1_ccp_eve_tranquility\cache’…
[warning] There are no market files for import!

@Oleg
Try to specify path to EVE Online client instead of cache folder.
Same problem:
[ok] Updating market orders (cache)…
[info] Importing from client at ‘C:\Program Files\CCP\EVE’…
[warning] There are no market files for import!
[info] Launch EVE Online and export any orders at Market window.
When I press import open DOS console window, but path in caption move to Temp directory.
Config file:
C:\Program Files\CCP\EVE
C:\bin\EVEMentat\Storage\Market Cache
But in “C:\bin\EVEMentat\Storage\Market Cache” no files
And sometimes I get follow error:
[error] Updating market orders (cache)…
[info] Importing from client at ‘C:\Program Files\CCP\EVE’…
[error] Не удалось найти часть пути “C:\bin\EVEMentat\Storage\Market Cache”.
@Oleg
Can be problem with access to folder where EVE Mentat is located.
Try to move EVE Mentat folder for instance to user’s Desktop.
Next time please send me your log.txt file (not here, via mail).
Move EveMentat to Desktop, try import but no log file found.
@Oleg
File log.txt should be near EVEMentat.exe file.
No file. I try import from cache folder directly EveMentat create in folder “C:\bin\EVEMentat\Storage\Market Cache” many CSV txt file with unknown data.
@Oleg
In general it’s impossible that EVE Mentat doesn’t create log.txt file when it has enough rights.
Do you use latest version of EVE Mentat?
Also it can be a problem with some settings of your antivirus or antispyware soft. Please check them.
There no antivirus software. Last version don’t work. Version 1.1.26.790 works, but sometimes get 255 error.
P.S. Можно писать по русски?
@Oleg
Я послал приглашение поговорить более детально в чате Google Mail.
i have exactly the same problem as oleg, im using newest version of evementat
@Rafina
1. Check the access rights of folder where EVE Mentat is placed.
2. Tell me your full path to cache folder.
hmm, now that i remember, after i cleared all my cache files from eve this started happening ? access rights should be ok, its in my desktop, if you mean with path to cache folder by “cache import tool” its C:\Program Files (x86)\CCP\EVE
and its “use client locations”
@Rafina
Please, send me a bug report with log.txt file (generated immediately after the failed import!) and screenshot of your cache import settings attached.
Hello
I have several instances of eve running on several machines. If i install Menstat on any specific machines it reads the cache from that machine fine. The issue I have having is in reading the networked caches.
I have shared with full permissions, mapped drives etc etc
Any one can advise on this?
Thanks
@Tread
I advice to post normal bug report with screenshots of cache import settings, detailed description how to reproduce the bug, attached log.txt file.
