# Prerequisites The decompiler requires the latest version of IDA. While it may work with older versions (we try to ensure compatibility with a couple of previous versions), the best results are obtained with the latest version: first, IDA analyses files better; second, the decompiler can use additional available functionality. The decompiler runs on MS Windows, Linux, and Mac OS X. It can decompile programs for other operating systems, provided they have been built using GCC/Clang/Visual Studio/Borland compilers. * 32-bit decompilers require the 32-bit version of IDA to run. * 64-bit decompilers require the 64-bit version of IDA to run. IDA loads appropriate decompilers depending on the input file. If it cannot find any decompiler for the current input file, no decompilers will be loaded at all. The GUI version of IDA is required for the [interactive](/8.4/user-guide/decompiler/interactive.md) operation. For the text mode version, only the [batch](/8.4/user-guide/decompiler/batch.md) operation is supported. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
