Out of memory when unzipping file

[Roaster]

Hi,

I'm trying to unzip a packed .gz file with the unzip action. The file is about 558 KB in size and unpacked (using Winzip) about 3.3MB.

The protocol says:

C:\Documents and Settings\user\My Documents\Velypse\dump_d0062892_20100224_0100.sql. gz -> C:\DOCUME~1\user\LOCALS~1\Temp\
C:\DOCUME~1\user\LOCALS~1\Temp\dump_d0062892_20100 224_0100.sql -> C:\Documents and Settings\user\My Documents\Velypse\temp
Out of memory
26.02.2010 21:54:40: Step '5 - Unzip SQL Dump' failed
26.02.2010 21:54:40: Build ended.

I'm running VB 7.2a in a VMWorkstation 7.x. There is enough harddisk space and I guess memory, too for this task. All folders do exist, btw.

Any hint why this fails?
