Hey I was using Windasm32 today and I loaded a .dll file and it told me this

enter image description here

I tried to increase my virtual memory on windows 10 to 12000 and the max to 12000 and restarted the computer and ran the windasm32 in admin and it still gave me this error. So, how can I fix this?

    do you really need to use the tool that is still mentioning Win 3.1? Why W32dasm and not some new one?

  • Because it has a more better way to show all string data references so I can find the text strings easier others like olydbg does not have this option it seems that I can find string references on windasm32 better than I can find them on ollydbg , ollydbg does not show some strings like windasm32 so yeah are you going to help me out on this issue of mine or ?

Windasm32 is a very old 32-bit program and is probably running out of the 2GB virtual memory space allocated for it by Windows (you should be able to confirm it using a tool such as VMMap). One possible workaround could be to set the IMAGE_FILE_LARGE_ADDRESS_AWARE flag in the PE Header which would give it an additional 1GB of address space, e.g using editbin:

editbin /LARGEADDRESSAWARE  windasm32.exe

However this may lead to bugs and/or crashes if the program is not prepared to handle addresses above 0x80000000. And it may still not be enough for the program you're trying to disassemble.

I would strongly suggest using another, more modern disassembler instead that can handle big files. If you can't find the functionality you need, ask a new question about it.

Try this. In the menu, click:

Disassembler -> Disassembler Options -> Enable extended memory

W32Dasm893 Fix

  1. Removed the restriction of the disassembler to the number of lines of code that leads to messages: "W32Dasm could only allocate enough memory to process XXXXXX lines of Text ..."
