W need an experienced Windows developer who has a solid experience in assembly language and tools such as OllyDbg. We have an add-in for Excel (a plugin) that works fine on Windows 7 but fails on Windows 10 Pro with an access violation error. We don't have the source code for the add-in, and we need to know why it fails and possibly fix it. Only individual freelancers will be considered. Please write "OllDbg" at the beginning of your bid so that I know you read the description of this project.

OllDbg OllyDbg Hi! My name is Konstantin. I'm an experienced high- and low-level Windows developer. I have a broad range of software development skills utilizing Win32 API and direct Windows kernel calls from C, C++, C#, etc. languages including Assembly language and raw machine byte code. I have implemented several Windows drivers and complex Windows API compatibility wrappers for cross-platform and cross-Windows-version x32 and x64 applications. I know low-level Windows structures and non-documented API calls. I have experience with Microsoft Office add-in development including functions interception and Office UI integration. I have necessary experience with code and data flow decompilation, analysis and reverse engineering. Can you please provide more details about this task to better estimate time frame and complexity? Namely, which Office versions are you aiming; on which other Windows versions add-in works well; have you tried Windows 7 x64 and/or x32; which programming language was used for the add-in creation, etc. With best regards, Konstantin

OllDbg or Ollydbg? anyway... I have experience in reversing x86/x64 and I'd be happy to take a look as long as you are sure the error is reproducible. If it is possible to patch I will patch it / find a work-around. Otherwise the best I can do is investigate the problem and report it to you! Please send me a message if you are interested.
