Software Installation Problem ...

Recommended Posts

I have downloaded from the Internet site  www.malwarebytes.com mwb-download/  the file mb3-setup-43841.43841-  TWICE  and when opening the file up, I am ask to choose my language and then I get a "Run-time error at 433:1049" each time.  This is preventing me from installing the program which I want too use for checking if the disk I intend to clone is free of malware and other virus  problems.  I'm using WIN XP SP3 on an IBM ThinkPad x41.  How should I proceed?

Check the system requirements: these are taken from the official Malwarebytes guide (page 3)

    PLEASE NOTE: Anti-ransomware protection is not supported for Windows XP or Windows Vista, due to architectural constraints.

  • CPU: 800 MHz or faster, with SSE2 technology. This includes most modern Intel x86 processors as well as AMD’s Athlon 64, Sempron 64, Turion 64 and Phenom CPU families. Please refer to the following page for further information:

Hello MAXBAR1!

Many thanks for your prompt reply.  Based on the specs you have provided, I checked my machine with BelArc Advisor and got these details:


CPU is 1.60GHz Intel Pentium M in  a Socket: mPGA478C;  supports instructions: MMX, SSE, SSE2

RAM for WIN XP is 256 MB, which is acceptable for my OS

Free disk space on Drive C   is 6.87 GB

Screen Resolution is 1024x768 TFT LCD Panel

The Internet connection works fine!

All of which seems to be in line with the required specs.  SO, what's the problem?

Hello, exile360 & MAXBAR1,

Have downloaded the legacy edition of Malwarebytes and have read the manual instructions provided by MAXBAR1.

Many thanks for the alternatives as I recall with joy my long-ago use of Malwarebytes in disposing of a malware bug that had plagued me on a different machine.  Malwarebytes is the way to go!


Once I've given the alternative edition a chance to do its thing, I'll let you know the results I've had.

Best regards,
