The program can't start because MSVCP100D.dll is missing from your computer. Try reinstalling the program to fix this problem

We may get this error when we try to execute an application which has CPP component. Here MSVCP100 is a file which should be installed along with Microsoft Visual C++ 2010 Re-distributable Package. Here 100 means 2010 and D means debug version. This error occurs only when you are trying to run your application which is compiled using the “debug” configuration instead of “Release”.

Here when you try to run the application which was the debug output, then it would expect the appropriate file which has the Debug version, when you don’t have visual studio installed on your machine, then you will experience this kind of issues.

You can fix it in three different ways. You only have to follow any of the below. The first two options are straight forward.

  • Install visual studio.
  • Build your application using release configuration.
  • Copy the files to system32 folder.

3. Copy the files to system32 folder

Here you can find the missing dll from internet but never ever do that! Those files could be contaminated either intentionally or unintentionally and it may help expose your machine to virus attack.

What you have to do is, find a machine which has visual studio 2010 installed, If you are running the application in a 32 bit machine, then go to C:\Windows\System32 and copy the missing file and place it in C:\Windows\System32 of the machine where you want to run your application.

If you are running your application in a 64 bit machine, then the folder where you have to copy the file is bit different. You have to go to C:\Windows\SysWOW64 and copy the missing files and paste it to C:\Windows\SysWOW64 of the machine where you have to run the application. This will help you fix the error.

In in case you have copied from system32 folder and you have placed in SysWOW64 folder, then you may end up getting an error like “The application was unable to start correctly (0xc000007b)”.

Parquet file experiments, findings and recommendations

Parquet is a binary file format designed with big data in mind where we must access data frequently and efficiently. The way it stores file on the disk is also different from other file formats. It is a column-based data file. And in reality it uses both row based and column based approach to bring the best of both worlds. The data is encoded on disk which ensures that the size remains small compared to actual data and is then compressed where the file is scanned as whole and cut out redundant parts. The query/read speed is dramatically fast when compared to other file formats. Nested data is handled efficiently which is quite cumbersome in other file format to achieve. Doesn’t require to parse the entire file to find data due to its way of storing data. This makes it efficient in reading data. Works quite efficiently with data processing frameworks. Automatically stores schema information. SQL querying is possible with this file format using Continue reading

Libish Varghese JacobI am currently working as a lead engineer in one of the leading wind turbine manufacturing firm. I have wide range of interests and getting my hands dirty in technology is one among them. I use this platform primarily as my knowledge base. I also use this platform to share my experience and experiments so that it might help someone who is walking the way I already did. The suggestions expressed here are the best to my knowledge at the time of writing and this may not necessarily be the best possible solution. I would pretty much appreciate if you could comment on it to bring into my notice on what could have been done better.
