Dear Students,

In the next lesson we will study the whoami crackme. However, it seems that the creator of the whoami crackme has built it as a debug built which  relies on debug versions of the following DLLs:

msvcp140d.dll, vcruntime140d.dll, and ucrtbased.dll

So, if your whoami cannot run, you have two solutions. However solution 2 below now is no longer working with Windows 11:

1. Install Microsoft Visual Studio 2022 Community edition. (Use this solution)

Just google for Microsoft Visual Studio 2022 Community edition - it will give you the 2026 edition - that is fine. It will work. During installation, make sure to select the C++ Development workload. This will ensure that the necessary debug runtime libraries are installed. When installing be sure to check only the following ones checked in red:

(1) MSVC Build Tools for x64/x86 (Latest)
(2) Windows 11 SDK (10.0.26100.7175)

Uncheck all the rest.

[ The solution below is now not working with latest Windows 11 - Do not use this ]

2. Download and unzip the file debug_nonredist.zip from the Resources section for Lesson:  Tracing EAX values and

copy the two folders x64 and x86 to the same directory as whoami crackme, or, to

the system directories C:\Windows\System32 (for 64-bit) or, C:\Windows\SysWOW64 (for 32-bit)
