Okay.... this did NOT work. However, I hacked the contents using certain tools and figured out the issue. To all who may face the same problem
- The link gives a RAR file. Unzip it somewhere temporary, for example: C:\Users\Downloads**\STM32Virtualcom_driver**
- Inside this folder, you'll have ANOTHER zip: STM32 USB转串口驱动 Virtual COM Port Driver(V1.3.1).zip
- In Windows Explorer, just go inside that zip folder.
- Here you'll find VCP_V1.3.1_Setup_x84.exe or just xxx_Setup.exe. DO NOT CLICK ON IT!!
- For your use case, for mine I needed the 64-bit one (as I have a 64-bit OS) take the file which is actually a self executable and UNZIP it 1st.
- When unzipping, unzip it in say C:\Users\Downloads itself.
- After unzip completes, you'll find a folder created in that above folder with strange Chinese characters.
8**. Rename that folder!!** I renamed t to STM32.
- Go inside STM32 and there'll find the same executable files listed above but it's not a zip file anymore.
- Now if you click on it - it'll install.
What support should have done - is provide 1 single zip/rar/7z file compressing the contents of STM32 files ONLY. They are capturing absolute file paths, which in their system are in Chinese and it's causing all sorts of issues
