Can u pls resolve it

推荐答案

这个错误信息有很多原因。请检查以下内容：

- 您正在编译32位应用程序，而不是64位。

- 因为您遍历位置检查文件夹的名称是否有效，尤其是如果这适用于某些文件夹。

There are quite a few reasons for that error message. Check the following:
- you're compiling 32 bit application, not 64.
- since you loop through the locations check that the names of the folders are valid, especially if this works for some folders.
