Compression Memory Requirements

The highly advanced compression technology used in InstallAware has very large memory requirements. When the compression slider is at the Best setting, you may need as much as 38 GB free physical memory for compression to complete. If you are getting errors during build that compression failed, install more physical memory on your development system, close running applications, or lower the compression ratio.

 Notes

• Compression memory requirements typically apply only when building your setups. Built setups, no matter how large or tightly compressed, work well with as little as 1 GB physical memory installed on the target system; as long as your compression dictionary size is below 1.5 GB.
• However, compression grades at or above a 1.5 GB dictionary size mandate a 64 bit operating system for successful extraction. Please note that you would not benefit from using larger dictionary sizes, unless your uncompressed data is at least as large as your dictionary size.
