I have recently bought a new computer, and thus needed to install Atlantica again. I have downloaded the client with no problem, and the installation went fine. However, when I open up the patcher I get the error message:

"There is limited space on the selected drive. You may experience
complications due to insufficient storage space. We recommend that
you clear enough space before you try again.

Installed drive and leftover free space - C:\ 5,178,588,304.00 TB
Recommended Free Space(Max) - 37.9 MB"

This makes no sense, and is clearly incorrect.
I am given three options: "Abort", "Ignore", and "Retry". Abort closes the patcher while the other two simply trigger the same message.

I have 1.21TB (terabytes) free space on C:// and no partitions. Atlantica is installed on C:// and all of its program files are there.

I have tried downloading the client from all all of the mirrors and always recieved the same error. I have tried downloading the manual patch and it still gave me the same message.

My computer specs:

Windows Vista Home Premium (64-bit)
Intel i7 920 @ 2.67GHz (4 cores)
6GB RAM
ATI Radeon HD 4800 (1GB)
1.5TB Hard drive (SATA)

I am very reluctant to partition my drive (which may not solve the problem). I have run virus-scans etc. and stress-tested my PC, all giving positive feedback. I have posted a ticket to NDoors, but have not received any reply thus far.

What can I do?

Thank you for your help!
 

I dont know if it would help, but alot of programs I have noticed need to be added to the "Data Execution Prevention" list.

Google the process for it.

Otherwise, contact AO's support area, because that is an error that Ive never seen before.

I have exactly the same problem.

I just changed PC and put some huge HD into; Atlantica launcher seems not able to read correctly such sizes.

I already opened a ticket, I won't partition my HD for sure... Atlantica will wait.
