Here is the Image and my whole Dilemma is explained. it will help you to understand better.
please have a look.
"Wallet-master" is the folder containing the source files you downloaded from GitHub, correct? You can place this folder wherever you like -- well, actually you managed to put it in one of the worst locations imaginable so I recommend you to place it somewhere else
(eg. C:/Wallet-master/ or into your Documents folder).
After you have moved the "Wallet-master" folder to a convenient location (preferably not within the nodejs Program Files folder),
1) enter the folder (it should contain all the files you see on the github page including a file called "package.json"),
2) open a commandline window inside the folder (eg. Right Click + Shift and then selecting "Open Command Line Window here"),
3) enter the command "npm run apply:bitcoincom" (ie. the whole line as described on the GitHub page -- not just the "apply:bitcoincom" part). Once you've done this you need to
4) open the JavaScript file "index.js" inside the folder node_modules > asn1.js-rfc5280 with a text editor. There at the top you should see some code that looks something like " try { ... } catch(e) { ... } " -- that's the bit that according to the readme you need to delete and replace with " var asn1 = require('asn1.js'); ".
5) Follow the remaining instructions of the GitHub page from there and you should be fine.
What are you trying to do anyway? Anything specific or do you simply want to avoid using precompiled binaries?
