When i use the CompressionMethod LZMA and the CompressionLevel xclHigh i get the following error messages for each file:

121 - An error occured while compressing. The data is probably incomplete.
107 - The reported CRC does not match the calculated CRC.

I get no error messages when i change the CompressionLevel to xclMedium.

Is the CompressionLevel xclHigh incompatible with the CompressionMethod LZMA? Didnt find any hints at the documentation.

I tested this with Vista SP2.

We're getting reports of exactly the same error ("An error occured while compressing. The data is probably incomplete.") with LZMA and high compression, but on Windows XP SP3, and it isn't for all files but just some and only sometimes. Xceed ZIP DLL version is 6.5.9562.0

Any fix for this?
